Title: Hybrid membrane/cryogenic process for hydrogen purification
Inventor: HOPKINS JEFFREY ALAN
IPC: C01B3/50
Filed: 1986-08-18
Granted: 1990-07-31
Abstract: ABSTRACT The present invention involves a process for recovering hydrogen from a feed gas mixture comprising hydrogen and at least one other component. The feed gas mixture is initially separated in a membrane separation unit to produce a hydrogen-rich stream and a hydrogen-lean stream. The hydrogen-lean stream is subsequently treated in a cryogenic separation unit to remove a portion of the non-hydrogen components and produce a hydrogen-enriched stream. The hydrogen-enriched stream from the cryogenic separation unit is recycled and combined with the feed gas mixture to the membrane separation unit.

Title: Security file system for a portable data carrier
Inventor: ANDERL EWALD C
IPC: G06F21/62
Filed: 1987-04-29
Granted: 1991-08-20
Abstract: SECURITY FILE SYSTEM FOR A PORTABLE DATA CARRIER            Abstract A file system for a portable data carrier provides improved security for files which support multiple applications, from custom repertory dialing to storage of individual medical and/or banking records. Although the portable data carrier looks and feels much like an ordinary credit card, it includes a computer and an electrically erasable programmable read-only memory. Power for operation of the portable data carrier is provided from an associated station via a reader/writer. The reader/writer also couples data between the data carrier and the associated station. The applications reside in multiple files in memory on the portable data carrier. Appropriate application software residing in the station, when accompanied by an appropriate password, enables the retrieval and modification of these files. A separate password is required for gaining access to each of designated levels of interaction between the portable data carrier and the associated station. Additional restrictions such as requiring an additional password for writing to a file and also allowing a user logged in at a particular security level to only append information to a file may be imposed in accordance with file security on the portable data carrier. And since each of the files may have its own security requirements, multiple applications may exist on the portable data carrier without conflict or confusion.

Granted: 1992-05-12
Abstract: Method and device for manufacturing bricks ABSTRACT     The bottom of a mould is provided with releasing material and thereupon filled with clay and trimmed off. The bottom is then moved, so that it is virtually outside the mould. There is friction force occuring between the side walls of the mould and the clay, as the side walls are not provided with releasing material in order to keep them smooth. These friction forces are overcome by an outward force applied to the bottom.

Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE                     OPTICAL DEVICE An optical device is disclosed which comprises an optical waveguide formed from at least a first material having a non-linear refractive index n2 coupled to a first pair of ports of an optical coupler.   An optical signal input at one of a second pair of ports of the coupler is split to provide two signals counter propagating around the waveguide  loop.    By selecting the coupling ratio  and appropriate waveguide parameters to ensure an asymmetry in the  device,  it  is possible  to  produce  an  intensity dependent  relative  phase  shift  between  the  counter propagating signals, whereby to vary the device output. Embodiments of the invention may be used to perform logic functions on, to amplify, switch or otherwise modify an input signal.

Title: Single-cylinder, truck-mounted brake assembly
Inventor: HART JAMES E
IPC: B61H13/24
Filed: 1987-11-25
Granted: 1992-05-19
Abstract: (Case No. 8410) ABSTRACT OF THE DISCLOSURE   A single-cylinder, truck-mounted brake assembly for a railway vehicle truck in which low-cost, lightweight, truss-type brake beams are employed, with one beam having the single brake cylinder mounted thereon.          Force-transfer levers pivotally-mounted to the respective brake beams at the beam-midpoint are interconnected by force-transmitting members that pass through openings in the bolster to move the brake beams into brake shoe/wheel engagement when a brake application is made.  The brake rigging is set up so that the transfer lever bail imparted to the force-transmitting members is split.          With respect to the force-transfer  lever connected to the one force-transmitting member (brake cylinder), this has the effect of the brake cylinder piston skewing equally on apposite sides of the cylinder centerline to prevent piston seal leakage.  In addition, diagonally-opposed lever arms of the respective force-transfer levers are greater in length than the other lever arms to obtain brake force multiplication without unbalancing the brake shoe forces.  A further advantage found by making the one transfer lever arm longer than the corresponding lever arm of the other transfer lever is to split the lateral swing of the further force-transmitting member (slack adjuster) equally on opposite sides of the centerline of the bolster opening to avoid interference therebetween.

Title: Precipitation gauge
Inventor: WANG TING-I
IPC: G01N21/53
Filed: 1988-02-02
Granted: 1993-02-23
Abstract: PRECIPITATION GAUGE                  ABSTRACT       A precipitation gauge is provided for remotely detecting precipitation and for measuring the rate of precipitation in an open environment, such as an aircraft landing field.  The system employs an optical transmitter and receiver, wherein particles of precipitation passing through a light beam from the transmitter cause scintillation at the receiver.  The spatial separation between the light transmitter and receiver is quite small, typically substantially less than one meter. The small separation between the transmitter and the receiver is made possible by the use of a partially coherent light beam, in place of a conventional laser beam.  The transmitter and receiver are spaced apart a distance of approximately 0.6 meters. The product of one half of the angle of incoherency multiplied by the spatial separation between the transmitter and receiver is preferably about 1.5 millimeters.  An output from automatic gain control circuitry is processed by signal processing circuitry
